If you are a high school student, you can learn to fly through the college entrance examination.

If you are a college student, you can realize your dream of flying through a "big change". Generally, undergraduates above sophomore year are required. Junior college is also possible, but at your own expense.

If you are a former student, you can also participate in the selection of recruiting flight students. Companies have different requirements for age and education. Generally, a bachelor's degree or above is required, and some, such as Shenzhen Airlines, also need a junior college. The age is generally required to be no more than 25 years old.

The reason why I said you asked strange questions. Mainly because, from your question, I can't see what you are asking: the requirement of recruiting flight students or the requirement of applying for airlines to become on-the-job pilots. If airlines recruit pilots, they don't look at your education. Some people who learn to fly at their own expense only participate in skills training and do not give academic qualifications. As long as you can get a license and CET-4, there are many companies vying for it. In addition, the physical examination standards of in-service pilots and pilots are different.
